I have a 2003 HCH with 78000 miles on it. I just had to replace my DC/DC converter due to corrosion for $1500. I tried to argue that my first battery went out after 3 years and it could have been caused by this unit (when the converter was still under warranty). I had a second battery go out after 2 years, and this is my third after 1 year. Seems like a pattern to me, dating back to the first, but they didn't buy it. Any one know of issues with this part? I'd really like to get out of this charge.
This ast February the IMA light came on and they replaced my IMA and ABS control units. Fortunately the IMA was under warranty and they gave me the ABS on "goodwill". I think this repair would have run near $3000+ if I had to pay it.
I also had the catalytic converter replaced this summer, but that was under warranty. It would have been $1000 or so.
So my car has undergone $5500+ in repairs this year, at only 78000 miles! Though I didn't pay most of it, I'm very worried about keeping this car much longer since I'm running out of the warranty period. Each repair has been very costly and I'm afraid of the future. I can't afford these costs on a single income, with a family coming, and my husband in school.
Do you think I've just had an unlucky year and it will be trouble free for awhile (and how long)? Maybe I've replaced all of the expensive stuff already. Or do you think I should trade this guy in for a new, cheaper to maintain "normal" car? I'm very afraid of the day the hybrid batteries go out.

I want to support hybrid, green, technology but I don't know if I can afford it until it develops further.
What are your thoughts?
